It will be quite awhile before it's anywhere close to common or mainstream to do EV swaps for performance. It will come but it's all about price/availability and of course performance being worth the swap as it improves/gets cheaper. Those doing it now will be like Hunter79764, for mpg/cost reasons on a daily commuter and people comfortable in handling the "new" technology. Took LS swaps maybe 10 years, very roughly, to go from avant-garde to commonplace. So EV I'd suspect is at least 10 years out from that trend. Plus there will be more natural resistance, some people like the natural combustion engine and the fun sounds and rumble they can make as part of the appeal.
